Abstract
The utility model provides a self-sealing structural valve. The self-sealing structural valve comprises a quartered ring, a compression ring, a seal ring, a gland box, a valve body, a valve seat, a valve rod and a gate, wherein the valve seat is connected with the valve body; the lower end of the valve rod is provided with the gate while the upper end of the valve rod is connected with the gland box; a cylindrical seal ring is arranged on the gland box; the compression ring which is an annular casting is arranged on the seal ring; and the quartered ring, which is an integrally annular casting composed of four wedge blocks having uniform shape, is arranged on the compression ring. The valve is the improvement and innovation of the conventional valve; the cylindrical seal ring is adopted and used for replacing a gasket; the quartered ring is adopted and used for replacing a stud; the self-sealing structural valve is reasonable in structure, simple in processing technology, easy to implement and convenient to maintain; and the external-leakage maintenance-free effect of the valve is realized, and thus the manpower and the material resources are saved.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of self sealing structure valve.
Background technique
Since China reform and opening-up, national economy obtains rapid growth, and " scientific and technical innovation, autonomous innovation " become the main flow of the present industrial development of China, and China's industry is progressively to intensive style, energy-saving and emission-reduction, the future development of low-carbon (LC).Valve is in fluid system, is used for controlling direction, the pressure of fluid, the device of flow.Traditional valve sealing structure adopts double-screw bolt compress gasket structure, the axial force of valve rod when double-screw bolt need bear the medium static pressure and open valve, so double-screw bolt is designed to thick especially shape, simultaneously, the material requirements of double-screw bolt is harsh.When double-screw bolt increases when thick, the valve body at this place need thicken simultaneously, has improved cost of production, has strengthened the casting difficulty.When the variation of pipe vibration or medium temperature, pressure caused the nut loosening of double-screw bolt, medium was easy to leak outside from this.When valve installation was on pipeline, appearance all can tightly wrap with thermal insulating material, also used the tin plate parcel outside thermal insulating material, when medium leaks outside, was not easy to seek leakage point, and the wrappage that must will be wrapped on valve and pipeline removes, and takes a lot of work, takes material, time-consuming.In order to address this problem, R﹠D institution and science and technology in enterprise personnel utilize modern science and technology in constantly research, exploration, although obtained technically some progress, still exist the technical barrier that not yet overcomes in practice.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, and a kind of self sealing structure valve is provided, and is rational in infrastructure, is convenient to maintenance.Seal ring is designed to cylindrical shape, and under the effect of pressure, seal ring can become sealing by the automatic tensioning open form, and pressure is higher, more easily sealing.Adopt four minutes rings to replace double-screw bolt, need not to increase wall thickness, reduced cost and difficulty of processing, improved the sealability of valve.
The technological scheme that its technical problem that solves the utility model adopts is: contain four minutes rings, pressure ring, seal ring, Stuffing box, valve body, valve seat, valve rod, flashboard, valve seat is connected with valve body, the lower end of valve rod is provided with flashboard, the upper end of valve rod is connected with Stuffing box, Stuffing box is provided with the cylindrical seal circle, seal ring is provided with pressure ring, pressure ring is a ring-type foundry goods, pressure ring is provided with four minutes rings, four minutes the ring be one by the domain foundry goods that piece forms of carving of four uniform shapes, formed a kind of self sealing structure valve.
The know-why that its technical problem that solves the utility model adopts is: existing valve is improved innovation, replace pad with seal ring, ring replaced double-screw bolt in four minutes.When valve uses, be rise or land by valve rod, the drive flashboard is close or lift off a seat, and realizes closing or opening of valve, thereby plays the control action to the medium in transporting system.During to seal ring, seal ring can become sealing by the automatic tensioning open form when the pressure-acting of medium.The pressure of medium is larger, and it is tighter that seal ring increases, and more easily sealing, and seal ring has certain seal angle, can not affect sealing because of pressure, temperature and vibrations, thereby realize the function that valve leakage out of steam system is non-maintaining.This valve adopts four minutes ring fit sealings, and because the periphery of four minutes rings can be anti-shearing, and the local shared valve body wall thickness of shear-stable seldom, so valve body do not need to increase thickness, has alleviated difficulty of processing, has saved raw material, and is easy to maintenance.
The utility model beneficial effect is: a kind of self sealing structure valve has carried out improving innovation to existing valve, adopts the cylindrical seal circle to replace pad, and ring replaced double-screw bolt in four minutes, and rational in infrastructure, processing technology is simple, is convenient to maintenance.Valve is reached leak outside non-maintaining effect, saved the human and material resources resource.
Description of drawings
The below further describes the utility model in conjunction with the accompanying drawings and embodiments:
It is a kind of structural representation of self sealing structure valve in figure.
In the drawings: 1. four minutes rings, 2. pressure ring, 3. seal ring, 4. Stuffing box, 5. valve body, 6. valve seat, 7. valve rod, 8. flashboard.
Embodiment
In the drawings: valve seat 6 is connected with valve body 5, the lower end of valve rod 7 is provided with flashboard 8, the upper end of valve rod 7 is connected with Stuffing box 4, Stuffing box 4 is provided with cylindrical seal circle 3, seal ring 3 is provided with pressure ring 2, and pressure ring 2 is ring-type foundry goods, and pressure ring 2 is provided with four minutes rings 1, four minutes the ring 1 be one by the domain foundry goods that piece forms of carving of four uniform shapes, formed a kind of self sealing structure valve.
Existing valve is improved innovation, replace pad with seal ring 3, ring 1 replaced double-screw bolt in four minutes.When valve uses, be to rise or landing by valve rod 7, drive flashboard 8 is close or lift off a seat 6, realizes closing or opening of valve, thereby plays the control action to the medium in transporting system.During to seal ring 3, seal ring 3 can become sealing by the automatic tensioning open forms when the pressure-acting of medium.The pressure of medium is larger, and seal ring 3 increases tighter, and more easily sealing, and seal ring 3 has certain seal angle, can not affect sealing because of pressure, temperature and vibrations, thereby realize the function that valve leakage out of steam system is non-maintaining.This valve adopts four minutes ring 1 fit sealings, and because the periphery of four minutes rings 1 can be anti-shearing, and local shared valve body 5 wall thickness of shear-stable seldom, so valve body 5 do not need to increase thickness, has alleviated difficulty of processing, has saved raw material, and is easy to maintenance.
